SUBJECT:
Calvert Cliffs Nuclear Power Plant Unit No.1, Docket No.' 50-317 . Inspection of Threaded Fasteners in the Reactor Coolant Pressure Boundary of PWR Plants
REFERENCES:
_(a) lE Bulletin 82-02, " Degradation of Threaded Fasteners in the Reactor Coolant Pressure Boundary of PWR Plants". (b) - Letter to R. C. Haynes-from A.. E. Lundvall, Jr., dated July 30,1982. (c) Letter to R. C. DeYoung from A. E. Lundvall, Jr., dated ~ October 1,1982 ^ Gentlemen: IE. Bulletin 82-02 ' established requirements for -Implementation of -Maintenance ' Procedures, inspections and Reports of examination results concerning certain Reactor. Coolant Pressure. Boundary Threaded Fasteners. Threaded fasteners at Calvert Cliffs - which were addressed in the Bulletin included 'those in (1) Pressurizer and Steam Generator Primary Manway Closures, (2) Valve bonnets, and pump flange connections on lines,six inches or greater' nominal pipe size. Reference (c). stated our intent to implement the Regulatory Guide 1.65 exclusion allowance for reactor. vessel closure - studs contained in IE Bulletin 82-02. This letter's purpose is to complete Action item 4 of the.IE Bulletin 82-02 for those fasteners examined during Calvert Cliffs Unit 1 1983 - refueling outage. - As required by Action Item 1 Calvert Cliffs Administrative and Maintenance Procedures-have been reviewed and updated where necessary to insure training of proper bolting / stud practices, detensioning and retensioning practices and gasket installation and controls. 4 {W '~ O 7 . 1 _. _ P m m o b /y{
Mr. Thomas E. Murley March 30,1984 Page 2 Action Item 2 of Reference (a) requires that whenever those connections identified in the scope of the Bulletin are opened for inspection or maintenance the threaded fasteners shall be removed (unless " seized" or interference fit), cleaned, and inspected per IWA-2210 and IWA-2200 of ASME Code Section XI. The component connections examined per Action Item 2 for the Unit 1 Cycle 7 refueling outage included: 1) #11 and
- 12 steam generator primary manways; 2) nine safety injection check valve bearing covers (1-51-215,1-51-225,1-S1-235,1-SI-245,1-51-118,1-SI-128,1-51-138,1-SI-148, and 1-51-227).
The visual and surface examinations performed on the steam generator manway studs and the safety injection check valve bearing cover studs showed no signs of degradation. Complete descriptions of the examinations performed and the results are included in Enclosure (1). It is our understanding that this transmittal completes the required written response requested under all actions items associated with IEB 82-02.
